Nov 3, 2023 · The heart is a muscular organ found in the middle mediastinum that pumps blood throughout the body. It is housed in the pericardial sac, which protects it and assists with its mechanics. Recalling from the heart anatomy, it has two atria and two ventricles that make up elements and important steps for the heart cycle.
Aug 4, 2023 · Myocardium (Middle Layer of Heart) Myocardium is the middle thickest muscular layer made up of cardiomyocytes. It is responsible for the contraction and relaxation actions of the heart.

The parts of your heart are like the parts of a building. Your heart anatomy includes: 1. Walls. 2. Chambers that are like rooms. 3. Valvesthat open and close like doors to the rooms. 4. Blood vesselslike plumbing pipes that run through a building. 5. An electrical conduction systemlike electrical power that runs through a building.
Your heart is in the front of your chest. It sits slightly behind and to the left of your sternum (breastbone), which is in the middle of your chest. Your heart is slightly on the left side of your body. It sits between your right and left lungs. The left lung is slightly smaller to make room for the heart in your left chest. Your rib cage protects...
Your heart looks a little bit like an upside-down pyramid with rounded edges. Large blood vessels go into and out of your heart to bring blood into and away from your heart. They connect your heart to the rest of your body, which it supplies with blood and oxygen.
The middle layer of the heart wall is the myocardium—the muscle tissue of the heart and the thickest layer of the heart wall. It is composed of cardiac muscle cells, or cardiomyocytes. Cardiomyocytes are specialized muscle cells that contract like other muscle cells, but differ in shape.
Oct 30, 2023 · The myocardium is the middle muscular layer of the heart. It is the thickest layer which lies between the single-cell endocardium layer, and the outer epicardium, which makes up the visceral pericardium that surrounds and protects the heart.
Oct 30, 2023 · The middle layer is the myocardium, and the innermost layer is the endocardium, which originated from mesothelial cells of the outflow tract. There are two major “pacemaker” centres in the heart that automatically generate an action potential.
